We call it a Flatbottom. Some call it a Bell. No matter. This all-around stirrup is built slightly wider across its base so your boot sits comfortably on the tread, unhindered by the stirrup sides. A slight rise, like an arch in a shoe helps set your foot for a good ride.**Item may not be in stock at our Weatherford location. If so, we will drop-ship it from the manufacturer.
